Investigate GPRD failed wikis

We have about 42 failed Wikis on the GPRD site:

failures = Geo::ProjectRegistry.failed_wikis
data = CSV.open('/tmp/failures.csv', 'w')
failures.each do |fail|
   data << [fail.project_id, fail.last_wiki_sync_failure&.gsub("\n", " ")]
end
data.close

It looks like most of these are due to ResourceExhausted errors?

# cut -d, -f2 failures.csv | perl -ne "s/'.*?'/TOKEN/g; s/[a-f0-9]{40}/HASH/g; s/stored in .*/stored in HASH/g; s/\bhttps?:\/\/.*? /URL /g; print"  | sort|uniq -c|sort -nr | more
